I recently completed a comprehensive heating and air conditioning repair service for a client. Upon arrival, I conducted a thorough inspection of the HVAC system to identify any issues. I found that the thermostat was malfunctioning, causing inconsistent temperature control. I replaced the faulty thermostat and calibrated the system to ensure optimal performance. Additionally, I inspected the air filters and ducts, replacing any that were clogged or dirty. The system was tested to confirm that both heating and cooling functions were operating correctly. The client was pleased with the restored comfort and efficiency of their HVAC system.
